These articles are spectacularly uninformed, jumbling together claims which have never been made, uninfomed guesses and lack of domain expertise. It is more interesting as a propaganda exercise, conceivably so Boeing/Dassault/Saab can sell their planes more competitively, or so the RADAR operator can get more government funding. Problems with the article: - The F35 isn't flown to air shows in 'war mode'. It has a bunch of reflectors added to increase its RADAR signature. It is only naked when it might be used in anger or over test ranges, and the USAF is very careful to make sure non-JSF program RADARs are off, or have the recordings deleted. - Passive RADAR is a real thing that works, but it only gives a general location. It would be meaningless to try to send a link track to an interceptor or SAM site from a passive RADAR system -- all you could do is call and say "look sharp chaps". - When you want to shoot at it, your S band (ground) or X band (interceptor) RADAR will have a very hard time picking it up or maintaining lock (because its signature changes depending on aspect, and obviously the pilot will manoeuvre to minimise). Meanwhile your ground receiver is getting jammed and transmitters are getting blown up by JDAMs. - Passive RADAR can also be jammed and deceived. How many times will you scramble interceptors for a false passive detection?
